Near-term consumption of groundwater for irrigated agriculture in the High Plains Aquifer supports a dynamic bio-socio-economic system, all parts of which will be impacted by a future transition to sustainable usage that ...

The enhancement of the 1 day strength of cementitious systems by a combination of calcium chloride (CaCl2) and diethanol-isopropanolamine (DEIPA) was studied, particularly in blended cement systems. A combination of ...

Glass cullet has been considered for use in concrete as a fine aggregate or a supplementary cementitious material (SCM). Glass reaction kinetics depends on both temperature and glass composition. Uniform composition, ...

Curing can help concrete reach its full strength and durability potential. The effect of sealing the concrete with plastic or formwork, use of a liquid curing compound, wet curing, and internal curing with saturated ...

Bridge deck temperature changes in the first few days after placement
due to the concrete heat of hydration and changes in ambient
conditions have long been identified as a significant contributor to
early-age cracking. ...

Over the years, many different simplified prediction methods have
been developed to predict the temperature development within
mass concrete members. This paper compares calculated temperature
values from three commonly-used ...

Methods are developed to study hydrologic interactions across the surficial/groundwater interface in a native prairie ecosystem. Surficial ecohydrologic processes are simulated with the USDA's EPIC model using daily climate ...

Groundwater and surface water interactions within riparian corridors impact the distribution of phreatophytes that tap into groundwater stores. The changes in canopy area of phreatophytes over time is related to changes ...

In this paper, we advance a theoretical framework for defining hyper-extractive coupled-systems in the United States. Our purpose is to extend a model constructed for an agricultural system in Southwest Kansas into a general ...

Problem: Gender differences of young drivers involved in crashes and the associated differences in risk factors have not been fully explored in the United States (U.S.). Accordingly, this study investigated the topic, where ...

The accurate prediction of thermal gradients in concrete calls for
models that characterize the temperature sensitivity of the hydration of
cementitious materials. The most common method used for this
purpose is the ...

The Kansas Department of Transportation (KDOT) has a comprehensive pavement management system known as Network Optimization System (NOS). Annual condition surveys are conducted for NOS. Currently Structural Number (SN) of ...

Statistical specifications for highway construction provide the means to measure the important quality control attributes and ensure their compliance. The pay adjustments in these specifications reflect the amount of pay ...

The mechanisms that contribute to early-age cracking are complex.
Determining the relative importance of each mechanism as well as
the combined cracking potential for a given concrete material is
essential for the ...

A signal-based pattern-recognition approach is used for structural damage diagnosis with a single or limited number of input/output signals. The approach is based on extraction of the features of the structural response ...

A simplified method of measuring concrete resistivity, as an index
of permeability, has been developed that is similar to ASTM C1202
or the rapid chloride permeability test (RCPT). It is significantly
faster and easier ...

Analytical solutions have been derived for the onset of strain localization in a broad class of unsaturated elastic-plastic porous materials based on Bishop’s definition of effective stress. Critical hardening moduli for ...

Free, large radial oscillations of multi-layered, thin, long, pipes are investigated using the theory of finite elastic deformations. The material of each layer is assumed to be homogeneous, isotropic, hyperelastic and ...
